Mermaids of Atlantis for Nintendo (NES)
Far below, from the dark and murky depths, another shiny bubble cluster
rises. Though very beautiful, the strangely quivering bubbles are part
of a sinister plan, concocted by the evil Emperor O-Dinten. With the
patented Dura-Bubble, he plans to profit from fun itself by controlling
all the games under the sea. Can you stop him and restore "The Freedom
to Have Fun" to the undersea world of Atlantis? It's a brain-bursting
bubble battle to pop thousands of beautiful bubbles before they overflow
to the open sea!
